CAR-VENTILATING SYSTEM.

Application filed September 2, 1919.

To (17/ whom it may con-061m. I

Be it known that I, PETER B. Bocanr, a citizen of the United States,residing at Milwaukee, county of Milwaukee, and State of IVisconsin,have invented new and useful Improvements in Car-Ventilating Systems, ofwhich the following is a specification.

Iy invention relates to improvements in car ventilators.

The objects of my invention are to provide practical and eflicient meansfor utilizing the motion of the car to not only deflect air into theinterior, but to prevent the entry of cindersyand to a large extent toexclude smoke; to provide tempering and distributing the air through thecoach and exhausting the foul air; ,and to accomplish the above objectswhile preserving all useful interior space, avoidinga detrimentalcharexterior projections of preserving the neat acter and substantiallyand attractive standard designs of railway 'cars in all respects whilesecuring adequate ventilation and complete change of air within the carevery few minutes while the car is in motion and at longer periods whenat rest.

In the drawings:

Figure 1 is a view, in horizontal section on line 11 of Fig. 2, showinga fragment of one end portion of the cupola or raised centralportion ofthe roof of a railway car, equipped with my improved ventilatingapparatus.

Fig; 2 is a vertical sectional view on line 22 of Fig. 1. f I

Fig. 3 is a sectional View on line 33 of Fig. 2.

.in the inner wall Like parts are identified by the same referencecharacters throughout the several views.

The railway car of which a fragment is shown in the drawings is ofordinary type except as to the ventilating apparatus herein described.

A set of air receiving chambers 1 isprovided, each chamber preferablyhaving the form of an elongated rectangular open endedbox fitted withscreens 2 at the respective ends, supplemented by additional s'creens ofne mesh woven wire 3, each within the chamber at a short distance fromthe associated end screen 2, and preferably obliquely placed to directcinders and other solid materials toward the inner wall 4. Thesechambers 1. each have an opening 6, 4, conforming generally to the sizeof the deck sash opening in cupola Specification of Letters Patent.

wall of the car to which the chamber is fitted, and at the margins ofthis opening 6, the chamber is secured to the walls of a pas sage 7WlllCll extends through the deck sash opening (the sash being removed)and de-- livers air from thereceiving chamber to a heating chamber 10,provided with suitable radiators preferably comprising a set of steamcoils 11, about which the air passes to an opening 12 and thence to theoccupied portion of the car.

he air receivingchambers 1 are provided with partition walls 13 and 14which extend from the outer wall of the chamber along converging curvedlines into the passage 7. The latter is preferably elbowed at 15 andextends toward the central portion of the car along the inner face ofthe cupola wall. A damper 16, preferably of the butterfly type, controlsthe air delivery and may be closed when, for

delivered through any given passage.

The chambers l are provided with false bottoms 20, preferably inclinedto an opening 19, through which solid material may fall to the openlongitudinal passage 21 between the false bottom and the main floor ofthe chamber 1. ended and cinders falling into it are thereforeimmediately blown out, the air acting with a slight aspirating effect todraw cinders through the opening 19. The cavities 22 between the screensmay be similarly provided with means for delivering cinders into passage21.

Within the heating chamber 10 deflectors 24 direct the air to the frontor inlet side of the radiator system. This chamber 10 is located withinthe cupola, above the level of the deck of the car and is'whollyinclosed by metal walls, the bottom wall 26 being downwardly inclined toform a cinder collecting cavity, and a wooden floor 27 may be providedbeneath it, the lower surface of which may be finished to correspondwith the interior finish of the car proper. The opening 12 is preferablyscreened by a suitable grid, and the size of the chamber 10 is such thatthe air therein has tle velocity so that dust lowed to settle. But thescreens in the inlet chambers exclude nearly all dust and cinders andalso check the velocity of the air, so that very little solid materialwill enter the heating chamber 10. The heat radiator in the ch m e s 10i l of course be subject to This passage 21 is open portion of thecontrol by suitable valves, in correspondence with requirements.

Each car is preferably equipped with two heating chambers 10, one neareach end, and one air receiving chamber 1, at each side of the cupola,fitted to the deck sash openings adjacent to the end of the car.Preferably the damper 16 on the side toward which the smoke of theengine blows will be closed and therefore each receiving chamber shouldbe of suflicient capacity to satisfy the requirements for a half portionof the car, a correspondingly located chamber 1 at the other end of thecar furnishing the remainder of the air supply. Each chamber 1 isadapted to receive air from either end and therefore the direction oftravel is immaterial.

Foul'air .from the floor of the car is delivered through grated openingsat 28 into exhaust stacks 29, which extend upwardly through the deck andare provided with suitably apertured caps 30 above the deck. To avoidinterference with the seating capacity of the car, these exhaust stacksare preferably located at or near the respective ends of the car, andpass upwardly along the side walls. They preferably pass through theroof between the end of the car and the heating chambers 10. Steam coilso'r ducts 31 preferably extend into these stacks, steam delivery theretobeing controlled in each case by a valve 32. \Vhen the car is at restfor any considerable time, air delivery through these stacks may beaccelerated by opening these valves and heating the columns of air inthese stacks I claim:

1. A car ventilator including the combination with one side wall of thecupola, of a horizontally elongated air receiving chamber secured tosaid cupola wall at one of its sides, and having screened open ends, apassage connected with the chamber and leading into the cupola, thewalls of said passage being adapted to deflect air entering through thescreened open ends and directed into the cupola, and a heating chamberwithin the cupola to which the passage leads, said heating chamberhaving an opening through which air may pass to the occupied car.

2. A car ventilator including the combination with the cupola of a car,of a horizontally elongated air receiving chamber having one of itssides connected to the side wall of the cupola, and having screened openends, curved partition walls sub-dividing said chamber in its centralportion, and passages leading into the cupola from the respectlve endportions, said partition walls being extended and constituting the innerside walls of the passages.

3. Acar ventilator includingthe combination with the cupola of a car, ofa hori zontally elongated air receiving chamber having one of its sidesconnected to the side wall of the cupola. and having screened open ends,curved partition walls sub-dividing said chamber in its central portion,passages leading into the cupola from the respective encLportions, saidpartition walls being extended and constituting the inner side walls ofthe passages, and a heating chamber within the cupola to which thepassages lead, said heating chamber having an opening for delivery ofair to the occupied portion of the car.

4. A car ventilator including the combination with a car body providedwith a cupola, of an exterior elongated air receiving chamber providedat each end withv a transverse screen and an interior obliquely disposedscreen spaced from the transverse screen to form a settling chamber,passage walls'leading from the central portion of the receiving chamberto the interior of the cupola, and depending walls forming a cinderdischarge passage extending underneath the receiving chamber, the bottomof the receiving chamber having apertures through which cinders may passfrom the settling chambers to the cinder discharge passage.

5. A car ventilator including the combination with a car'body providedwith a cupola, of an exterior elongated air receiving Ehamber providedat each end with a transverse screen and an interior obliquely disposedscreen spaced from the transverse screen to form a settling chamber,passage walls leading from the central portion of the receiving chamberto the interior of the cupola, and depending walls forming a cinderdischarge passage extending underneath the receiving chamber, the bottomof the receiving chamber having apertures through which cinders may passfrom the settling chambers to the cinder discharge passage. the spacewithin the cupola being subdivided to form a heatingchamber providedwith an outlet leading to the interior of the car body and havingtransversely extending superposed heating coils interposed in the pathof the air passing from the receiving chamber to the heating chamberoutlet.

6. In a car ventilating system a set of passage ways extended throughthe deck openings of the cupola and provided with exterior air receivingchambers having air inlets in their front and rear walls, andintermediate, deflecting partitions adapted to direct air from theinlets to the interior of thecar, said chambers being each provided withopen passage ways extending along their lower sides from one end to theother, and means for delivering cinders from the air receiving portionsof the chamber into such passage ways.

In testimony whereof I afiix my signature.
